This fixes visual artifacts in the first macroblock row of encoded
MPEG-4 video output caused by 8 additional lines of luma data leaking
into the chroma planes of the internal reference framebuffers: the
buffer size is rounded up to a multiple of 16x16 macroblock size, same
as for the h.264 encoder.
